Tile Installation Guide

Mosaic tiles can be a beautiful addition to any room, whether it's a backsplash in the kitchen or a feature wall in the bathroom. However, the installation process can be daunting for those who have never done it before. That's why we've put together this step-by-step guide to help you through the process.

Materials Needed:

  • Mosaic Tiles
  • Tile Adhesive
  • Tile Spacers (Optional)
  • Laser Level (Optional)
  • Notched Trowel
  • Tile Cutter
  • Grout
  • Grout Float
  • Sponge

Step 1: Measure the Area

Measure the area where you want to install the mosaic tiles. Make sure you have enough tiles to cover the entire area, plus a few extra in case of mistakes or damage.

Step 2: Clean the Surface

Clean the surface where you will be installing the tiles. Remove any debris, dust, or grease using a cleaning solution and a clean cloth. It's important that the surface is level since the tiles can highlight the wall's unevenness. You can install a cement board as backing to make sure the surface is flat and dry but it is optional.

Step 3: Prepare the Tile Adhesive

Mix the tile adhesive according to the manufacturer's instructions. It's important to mix small batches of adhesive to prevent it from drying out before use.

Step 4: Apply the Tile Adhesive

Apply tile adhesive to the wall with a trowel. Place the tile on the wall and press it firmly into the adhesive. Use tile spacers to create even gaps between the tiles and layout the full tile sheets first. Use a laser level to ensure that each tile is straight and even.

Step 5: Cut the Tiles

Use a tile cutter or tile nippers to cut tiles to size if needed. 

Step 6: Allow the Adhesive to Dry

Allow the adhesive to dry according to the manufacturer's instructions. This can take anywhere from 24 to 48 hours.

Step 7: Apply the Grout

Once the adhesive is dry, remove the tile spacers and apply grout using a grout float. Spread the grout over the tiles, making sure to fill in all gaps.

Step 8: Wipe Away Excess Grout

Use a damp sponge to wipe away any excess grout from the tiles. Allow the grout to dry according to the manufacturer's instructions

Step 9: Buff the Tiles

After the grout is dry, use a dry cloth to buff away any remaining haze on the tiles.

Step 10: Apply the Sealant

Seal mosaic tile grout for durability, especially in damp areas. Use recommended sealant and apply once grout is dry. Apply sealer to the whole surface and wipe away excess as it dries.


Installing mosaic tiles may seem intimidating, but by following these steps, you'll be able to achieve a professional-looking finish. Remember to read the manufacturer's instructions for each material carefully and take your time to ensure that each step is done correctly. Good luck with your project!
